Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE STERILIZER George J. Dyckes, Erie, Pa., assignor to American Sterilizer Company, Erie, Pa., a corporation of Pennsylvania In introducing steam to sterilizers difliculty has been experienced in obtaining a uniform distribution of the steam and the avoidance of air pockets. Such air pockets prevent the steam from reaching all parts of the sterilizer chamber and consequently interfere with a satisfactory sterilization of all the contents of the sterilizer. The present invention is designed to obviate this difliculty. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:-

Fig. 1 shows a sterilizer chamber in section.

Fig. 2 a section of the steam delivering means.

Fig. 3 a plan view of the deflector plate.

Fig. 4 a section on the line 4-4 in Fig. 3.

1 marks the sterilizer chamber. This is supported on a frame 2 and supplied with the usual door casing 3 for a door (not shown). A steam' 2o inlet 4 leads to a steam jacket 5 and the steam jacket 5 leads by a port 6 to a controlling valve '7, this being supplied with the usual exhaust 8. The controlling valve delivers steam through a jet opening 9.

A deflector plate 10 is provided with a guard segment 11 on its rear edge which engages the bottom face of the valve. The plate is secured to the bottom of the valve by screws 12 which extend through openings 13 in the plate. A steam opening 14 extends through the plate 10 in approximate alinement with the jet opening 9. Preferably the opening 14 is somewhat smaller than the jet opening 9, or at least smaller than the area of the jet delivered by the opening 9.

In the operation of the device the greater portion of the steam strikes the upper surface of the plate 10 and is deflected laterally along the upper part of the wall of the sterilizer chamber.

0 A portion, however, of the steam passes through the opening 14 and extends down the front wall of the chamber as defined by the door. This ver tical jet meets the lateral jet in the bottom of the sterilizer and prevents the formation of air pockets in the chamber. I have found it desirable to give a slight downward deflection to the upper face of the plate as shown so that while the upper jet follows in a general way the upper wall it preferably has a slight downward inclination from the point of delivery toward the rear.

What I claim as new is:-

1. In a sterilizer, the combination of an enclosed sterilizer chamber; and means supplying steam to the top of the chamber comprising devices dividing the incoming steam into a plurality of jets, one directed along the upper wall of the chamber and another directed along a vertical wall of the chamber.

2. In a sterilizer, the combination of an enclosed sterilizer chamber; and means supplying steam to the top of the chamber comprising devices dividing the incoming steam into a plurality of jets, one directed along the upper wall of the chamber and another directed along an adjacent integral wall of the chamber.

3. In a sterilizer, the combination of a sterilizer chamber; an inlet fitting secured in the wall of the chamber and delivering steam thereto; and a deflector plate on the inner end of the fitting dividing the incoming steam into a plurality of jets, one along a top wall of the chamber and.

another along an adjacent vertical wall of the 35 chamber.

4. In a sterilizer, the combination of a sterilizer chamber; an inlet fitting secured in the wall of the chamber and delivering steam thereto; and a deflector plate on the inner end of the fitting dividing the incoming steam into a plurality of jets, one along a top wall of the chamber and another along an adjacent vertical wall of the chamber, the jet along the top wall being in- 5 clined downwardly therefrom.
